Gas sensor for ammonia detection based on poly(vinyl alcohol) and polyaniline electrospun
(Wiley-Blackwell, 2019-04-05)
In this article, the results of the process and fabrication of ammonia gas sensors are obtained through the production of poly(vinyl alcohol) and polyaniline (PVA/PANI) nanofibers in different concentrations deposited on ...
An optical sensor for measurement of gaseous ammonia
(Elsevier Informacion Professional, S ABarcelonaEspanha, 2000)
Applicability of ammonia sensors for controlling environmental parameters in accommodations for lamb fattening
(2018)
Electrochemical ammonia sensors were used to analyse the existing relationship between the ammonia concentration and ambient levels of both temperature and relative humidity in commercial lamb fattening housing equipped ...
AlGaN double-walled nanotubes as ammonia gas sensor
(2020-12-01)
Nanotubes are one-dimensional material that has been proposed for many different applications, i.e. electronic devices and gas sensor. Due to their reduced size, extended surface area and stability they can represent an ...
Evaluating the performance of polypyrrole nanowires on the electrochemical sensing of ammonia in solution
(ELSEVIER SCIENCE SALAUSANNE, 2013-08-02)
This work encompasses the direct electrodeposition of polypyrrole nanowires onto Au substrates using different electrochemical techniques: normal pulse voltammetry (NPV) and constant potential method with the aim in applying ...
Use of Nafion (R) membranes for the construction of optical sensors for pH measurements

Hybrid layer-by-layer (LbL) films of polyaniline, graphene oxide and zinc oxide to detect ammonia
(2017-01-01)
Reliable gas sensors operating at room temperature are in demand for monitoring the environment for hazardous pollutants, such as ammonia (NH3) gas that may become toxic to humans and animals above a threshold concentration. ...
Colorimetric determination of ammonia in air using a hanging drop
(Marcel Dekker Inc, 2003-01-01)
A simple and sensitive method for determining atmospheric ammonia (NH3), using a hanging drop, is described. A colorimetric sensor is composed of two optical fibers and the source of monochromatic light implemented was a ...
